Kale....my dtr loves it and so does my dil....they make salads soups and kale chips which are very good...and its extremely healthy for you...
love beets....okra...not so much...brussel sprouts only if they are cooked in a vinegar brine then sliced up and cooked the rest of the way in butter/olive oil and garlic...
Your appreciation of kale, can also depend on the variety> I would recommend the Lacinato Kale (Also called Tuscan Kale, Dino Kale, Black Kale) as being a common variety that is easier to eat than really curly kale)
